LOCK-BLOCK FOR STEEL 13ED-SPRINGS.

Specification of Letters Patent.

Patented Mar. 23, 1920.

Application filed. .Tu1y 18, 1919. Serial No. 311,706.

the spring mattress frames carried thereby;

more particularly relating to the casting i'nember employed for connecting the side rails with head and foot angle iron crossbars to which the so-called spring bed bottoming or mattress-supporting wire structure is connected.

The principal object of my invention is to avoid the riveting of the bed bottoming angle iron cross-bars at the ends of the same to the brackets or coupling members carried by the side rails. To this end, the coupling members to which my invention is applied comprise unitary castings, including the usual socket for receiving the side "ail and the side wing heretofore employed and to which the angle iron cross-bars of the bed bottoming were riveted. According to my invention 1 provide the side wings of these coupling members with means whereby the angle iron cross-bars may be secured thereto wlthout riveting.

In the preferred construction, the side wing is double-walled, providing a slot to receive the angle iron cross-bars oi the bed bottoming or mattress-supporting structure; such slot having at some point intermediate its ends a cross-bar or member integrally united with the casting. This bar may be part of the casting proper, or a pin, rivet or the like may be set in the mold and connected with the walls in the casting operation. The cross member of the slot is adapted to cooperate with a slot or notch formed in the edge of the angle iron crossbar.

It will be understood, of course, that modifications of this arrangement are within the scope of my invention, and that in lieu of the duplex side walls forming the slot, the bracket or coupling member may carry a projecting rivet suitably headed and adapted to engage the slots of the angle lron crossbars of the spring bed bottoming, or a headmay be secured to the same,

" t new mitates t e fla end-S i the bracket may be slotted to receive the depending portion of the angle iron crossbars.

These and other features oi my inven' tion are more fully described hereinafter, reference being had to the accompanying drz-iwings, in which:

Figure 1, is a perspective view of the coupling member or bracket made in accordance with my invention, illustrating one of the angle iron cross-bars in proper position with relation thereto.

Fig. 2, is a plan view of the coupling member or bracket.

vFig. 3, is a sectional view on the line IIIIII, Fig. 1, showing the angle iron cross-bar in position.

Fig. 41, is a View similarto Fig. 3, illustrating a modification of my invention, and

Figs. 5, 6 and 7, are views illustrating other modifications within the scope of my invention.

In the drawings, 1 represents the side rail of a bed spring frame, and 2 one of the angle iron cross-bars to which the spring bed bottoming or mattress-supporting structure is connected by the spring links 3. Carricd at the end of the side rail is a coupling member or bracket 4; each corner of the mattress-supporting frame or spring bed bottoming being connected to one of these coupling members.

The coupling members or brackets i inelude a horizontal tubular part or socket 5 for receiving the end oi theside rail 1, and

surmounting this socket is arib or wing (i extemling upwardly and outwardly away from the plane of the socket. In addition, there is an extension member l projecting laterally from the bracket, and extending upwardly from the same is a rib or wing 8 which may be similar in general contour to the member 6, but smaller in cross sectional area. The rib or wing members 6 and 8 are connected together at the top by an integral side piece 9, and they provlde bearing surfaces 6 and 8, upon which the angle iron cross-bar 2 may rest.

Paralleling the side portion 9, is a wall 10 integrally connected with the coupling member or bracket, and forming with the side wall 9, a slot 11 receiving the depending edge 2 of the angle iron cross-bar 2. Intermediate the ends of this slot 2. pin or cross piece, preferably circular in cross section, is provided; the same being indicated at 12, and this is designed for coaction with a slot 13 in the depending portion 2 of the angle iron cross-bar whereby the latter may be locked to the coupling or bracket. This pin or cross member may be cast integral with the metal forming the coupling member 4, as shown in Fig. 3, or, if desired, the

' walls 9 and 10 forming the slot may be cast time and labor. I

It will be understood, of course, that modifications of this arrangement are with-. in the scope of my invention, and that in lieu of the duplex side walls forming the slot 11, the bracket or coupling may carry a projecting rivet 15 adapted toengage the slot. of the angle iron cross-bars of the bed spring bottom, as shown in Fig. 5; or a headed screw bolt 16 may be threaded into the side wall of the same, as shown in Fig. 6, or that in some instances the rib or wing members 6 and 8 of the bracket or coupling member may be slotted, as indicated at.17, to receive the depending flange 2 of the angle iron cross-bar 2, as shown in Fig. 7. With this arrangement, a rivet 18 may also be employed for cooperation with the slot 13 of the angle iron cross-bar.

While it is understood that the construction I have developed is detachable, the connection, when made, is relatively permanent and may remain in a permanent state as long as the bed is in use; detachable, however, if separation isdesired at any time.

I claim:

1. The combination with a corner member for bed springs or mattress-supporting frames and the like having a socketed portion attachable to the side rail of the structure and an upwardly extending portion integral therewith, of a projecting element carried by said upwardly extending portion for cooperative engagement with an angle iron cross-bar to which the mattress-supporting structure is attached; said angle iron cross-bar having a slot opening through its bottom edge to engage the projecting element.

2, In a corner member for bed springs or mattress-supporting frames and the like, the combination of a socketed portion attachable to the side rail of the structure, an upwardly extending portion carried by said socketed portion and including paralleling walls forming a slot, and across member extending across the space of said slot intermediate the ends and top and bottom of the same for cooperative engagement with an angle iron cross-bar to which the mattresssupporting structure is attached, said cross bar having a horizontally elon ated slot opening through its bottom edge or the reception of said cross member.

8. In a corner member for bed springs or mattress-supporting frames and the like, comprising a socketed portion attachable to the side rail of the structure, an upwardly and outwardly extending portion integral with said socketed portion and having parallel walls forming a slot, and a pin or bar extending across said slot intermediate the ends and top and bottom of the same, and a cross bar on said mattress supporting frame having a horizontally elongated slot opening through its bottom edge for cooperative engagement with said pin or bar.
